So this is what John Wick had in his suit

[–] [email protected] 5 points 2 months ago (2 children)

I loved those movies but they went way to hard into that suit in the later movies. I got ridiculous lol.

My favorite part was when he held the jacket up like a curtain. The material may be bullet proof, but the bullet will still push it out of the way like that lol.

I don't know if this will actually pan out the way that they imply in the title; armor needs to have a lot of different characteristics in order to be practical. As in, resistance to heat and cold, resistance to acids, alkalines, petroleum distillates, salts, UV, and oxygen, and also resist deformation. Multiple materials have displays significant promise for armor, but had a very short lifespan in real-word conditions. For instance, there was a material trademarked as Zylon that was supposed to be better than Kevlar, and it was used extensively by Second Chance (a body armor company); several cops were killed when their armor failed, and the armor failed because of exposure to sweat and ambient heat.

Yeah, this is a super cool development, but remember that everything that comes out at this stage is hype.

The armor works perfectly fine as long as it's not exposed to oxygen. But when's that ever going to happen?

[–] [email protected] 5 points 2 months ago (1 children)

Layer it with Kevlar and good?

[–] [email protected] 4 points 2 months ago

It really depends on whether it can be made to meet all the other criteria required for armor. I think that it's too early to make any good predictions.

Yes... that's why they use the word "could". This is how research works and what reasonable science reporting looks like. There were no promises or wild claims made in the article.

Could this be used to make a space elevator?

What about a space escalator?

[–] [email protected] 8 points 2 months ago

Escalator is smart, because if it breaks, you can still walk to space.

[–] [email protected] 5 points 2 months ago

I heard it was for lifts only

it's very lightweight though, so it could reduce plastic usage by mass, by reinforcing plastic/other materials.

There's also no reason why polymers need to be made out of oil: See PLA, cellophane, viscose, etc.

[–] [email protected] 7 points 2 months ago

I mean, we have tried to completely stop, or at least slow, the refinement of crude oil, because there's so much fucking byproduct that is made from it and is subsequently recycled and converted into plastic. What else can we do with all that fucked up petroleum byproduct besides make it all into some form of usable plastic?

[–] [email protected] 6 points 2 months ago (1 children)

Whether or not it’s plastic isn’t as big an issue as whether or not it’s biodegradable within a realistic timeframe.

[–] [email protected] 2 points 2 months ago

everything is degradable with enough heat

[–] [email protected] 5 points 2 months ago

Microplastic, even

[–] [email protected] 2 points 2 months ago

I'm sure it will mix well with the depleted uranium smoke the targeted crew will already be breathing.

Goes on to form company called General Products, builds spacecraft hulls. 😉

[–] [email protected] 6 points 2 months ago

Please, could we move to Known Space?

[–] [email protected] 13 points 2 months ago (1 children)

I can't wait to find out how toxic this is.

hello I would like to order a thousand full plate mails

[–] [email protected] 4 points 2 months ago

China, please respect this secret. Its made up with grapheme threads. Its impossible to understand exactly so we made a little picture with the molecules and such so you can't copy it.

[–] [email protected] 3 points 2 months ago

I'll be eager to know what the results will be about it's resistance to bullets and sharpened objects.

[–] [email protected] 2 points 2 months ago (1 children)

Surely I can't be the only one who thought this were interleaved DNA chains
